What causes food vacuum packaging bags to become sticky?

Vacuum packaging bag technology originated in the 1940s, and since the successful application of plastic film in commodity packaging in the 1950s, vacuum packaging bag technology has developed rapidly. Widely used for packaging meat, poultry eggs, chicken feet, miscellaneous grains, nuts, and other foods. But when using it, we often encounter situations where the bag becomes sticky. So, what is the reason for the stickiness of food vacuum packaging bags?

Cause analysis:

1. During the printing process, the drying speed of the ink is not suitable for the printing speed, resulting in some solvents remaining in the ink layer after printing, softening the ink layer and causing the composite film to become sticky.
2. The adhesive is not dry, and residual solvents gradually penetrate into the ink layer, causing the ink layer to soften and become sticky.
3. The plasticizer in the plastic film migrates to the ink layer, causing the film to soften and become sticky.

Handling measures:

1. Adjust the drying speed of the ink according to the actual situation and make it fully dry.
2. Adjust the process parameters to ensure that the adhesive is fully dried and control the amount of residual solvent.
3. Replace the plastic film.
